As a stormwater outfall, it is part of the broader network of facilities managing urban and industrial runoff in the region. In the United States, stormwater outfalls like Tanner Asphalt are regulated under the Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) permit program. Industrial facilities are typically required to obtain coverage under a Multi-Sector General Permit (MSGP) or an individual permit, which mandates the implementation of stormwater pollution prevention plans (SWPPPs) and regular monitoring of discharges.
